Abstract:

To build an agent that acts intelligently and can be given high-level instructions about what to do, one needs to give it a knowledge base containing information about its environment and capabilities, and methods for reasoning about the effects of its actions, revising its knowledge when it makes observations, and predicting the actions of other agents. This requires addressing the following knowledge representation issues: * Capturing the Prerequisites and Effects of Actions: A method is needed to represent succinctly the conditions under which actions can be performed (their prerequisites) and the conditions that they are expected to change (their effects). The "frame problem " concerns the effects of actions: how can they be specified without requiring one to stipulate explicitly the numerous conditions not affected by the action. * Perception and Other Knowledge-Producing Actions: For embodied
